摘　　要：分析了斗轮堆取料机的产尘机理,针对斗轮堆取料机,提出了射流自激雾化除尘技术。分析射流自激雾化除尘的机理,研究了射流自激雾化除尘系统中的喷射流量、喷射速度、斗轮旋转速度、喷射流与装载斗的接触角等关键参数对除尘效果的影响。现场实践证明,射流自激雾化除尘技术与其他除尘技术相比,优势非常明显:其系统结构简单、投资少、运行可靠;维护简单,无二次处理和二次污染;抗自然风能力强;除尘效率在80%以上。该除尘技术是斗轮堆取料机良好的除尘方式。This paper analyzes the mechanisms of dust production in bucket wheel stocker and reclaimer,and proposes water spraying dust-settling technology of self-impingement liquid jet for this machine.Some key parameters of affecting the efficiency of dust control in the water spraying dust-settling of self-impingement liquid jet are investigated,such as flow rate,spraying velocity,rotary speed,jet injection angle between jet flow and loading bucket etc.The practice showed that this water spraying dust settling of self-impingement liquid jet had more ideal effect than other de-dusting technology.It has feature of simple structure,less investment,reliable operation,and easy maintenance without secondary pollution.Due to its high wind resistance ability,dusts can be controlled to be over 80%.So this technique is a good dust removing way for bucket wheel stocker and reclaimer.
